' IMPROVEMENT IN Ptows.-

Specillcation forming part of Letters Patent No. 73,606, dated January21, 1868.

To all whom t may concern:

Be it known that I, W. T. HOWELL, of Alfred, in the county of Alleganyand State ot' New York, have invented a new and Improved Plow; and I dohereby declare that the following is a full, clear, and exactdescription thereof', which will enable others skilled in the art tomake and use the same, reference being had to the accompanying drawings,forming a part of this specification.

This invention relates to a new and useful improvement in that class ot'plows which are commonly termed sho\'elplows;7 and it consists in anovel and improved manner of attaching the blade or share to itsstandard, as hereinafter fully shown and described, whereby a very iirmattachment of the same to the standard is obtained, and one which willadmit ot the share being very readily applied to and detached from thestandard.

In the accompanying sheet of drawings, Figure l is a perspective viewotl a plow provided with my improvement; Fig. 2,- a detached view ot' asteel point pertaining to the same; Fig. 3, a rear perspective view ofthe lower part of the same.

Similar letters of reference indicate corresponding parts.

A represents the beam ot' a plow, and G C the handles, the lower ends ofwhich are secured to the same by a single bolt, a. D represents theplow-standard, with the upper part ot' which the rear end of the beam isframed. This standard has an inclined position, and its lower part, b,is of cylindrical form, as shown clearly in Fig. 3.

E represents the share, which is made of iron or steel, and if of thelatter material the point and share may be made out of one piece. Theshare has oblique sides o c, with a sharp ridge, d, extending` its wholeheight, from the lower end or point to the center of the top, which ishollowed out, so as to have quite a recess or depression, e, as shownclearly in Fig. 1. The share has a band, F, attached to its rear side,and this band is tit'tvd on the lower cylindrical part, b, ot' thestandard, and rests upon a metal pin, 0*, which is driven into thestandard, as shown clearly in Fig. 3. The share is prevented l'romturning on the standard D by means of a brace-rod, FX, the front end ot'which is hooked in the lower end of a bolt, G, which passes verticallythrough the beam A, and has its rear end passing through the standard D,the rod Il being in the recess or depression e in the top ofthe share,as shown clearly in Fig. l, and consequentlypreventing the share fromturning.

In case cast-iron shares be used, i have a steel point, H, shown in Fig.2, secured to the lower end of the share, said point being ot' V shape,to conform to the shape ofthe share.

The plow thus consructed is extremely strong and durable, and a brokenor worn share may be detached trom the standard and ,a new one appliedwith the greatest facility.

Having thus described my in rention, l claim as new and desire to secureby Letters Patent- The attaching ot' the share Eto its standard D bymeans ot' the band F, fitted on the cylindrical part b ot' the standard,the pin 0X on which the band rests, and the brave-rod F", fitting in therecess or depression e in the top otl the share, all arrangedsubstantially as g shown and described.
